Objective To explore the correlative factors affecting the compl ications resulting from cement leakage after percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral body compression fractures (OVCF). Methods From February 2005 to October 2008, 71 patients with OVCF were treated by PKP and were retrospectively analyzed. There were 16 males and 55 females, and the average age was 71.5 years (range, 52-91 years). The average duration of disease was 5.7 months (range, 1-11 months). A total of 171 vertebra were involved in fracture including 19 cases of single vertebral fractures, 21 cases of double vertebral fractures, 20 cases of three vertebral fractures, and 11 cases of more than three vertebral fractures. All the treated vertebra were divided into acute (86 vertebra) or subacute (85 vertebra) state based on changes in MRI signal intensity. There was no radiculopathy or myelopathy. The average injected cement volumewas 4.6 mL (range, 1.5-6.5 mL). The treatment efficacy was assessed by observing the change in anterior and middle vertebral column height, Cobb angle, visual analogue scale (VAS) and Oswestry functional score at preoperation, 3 days after operation and last follow-up. The patients were divided into cement leakage group and no cement leakage group. All the compl ications were recorded, and then the correlative factors affecting the compl ications were analyzed. Results All the cases had rapid and significant improvement in back pain following PKP. All patients were followed up for 14 months (range, 7-18 months). There was no cement extravasation resulting in radiculopathy or myelopathy. Four patients (5.63%) had lung-related compl ications. During the follow-up, 9 recurrence vertebral fractures were observed in 6 patients (8.45%). The anterior and middle vertebral column height, Cobb angle, VAS and Oswestry score were significantly improved when compared with preoperation (P lt; 0.05). Cement leakage occurred in 17 (9.94%) vertebral bodies; of 17 cases, the cement leaked into the paravertebral space in 7 cases, intervertebral space in 6 cases, channel of needl ing insertion in 3 cases, and spinal canal in 1 case. Univariate analysis showed statistically significant differences (P lt; 0.05) in preoperative anterior and middle vertebral column height, injected cement volume and vertebral body wall incompetence between the cement leakage group and no cement leakage group. There were no significant differences (P gt; 0.05) in preoperative Cobb angle, freshness of vertebral fracture, location of operative vertebrae and operative approach between the two groups. Multiple logistic regression analysis showed that the injected cement volume [odds ratio (OR)=3.105, 95% confidence interval (CI)=1.674-5.759, P lt; 0.01] and vertebral body wall incompetence (OR=11.960, 95%CI=3.512-40.729, P lt; 0.01) were the predominant variable associated with the compl ications resulted fromcement leakage. Conclusion The injected cement volume and vertebral body wall incompetence were the factors affecting the compl ications. The improvement of surgical technique is the capital factor that may reduce the compl ications in the PKP.
To explore related factors of cubital tunnel syndrome caused by cubitus valgus deformity so as to provide theoretical basis for the cl inical treatment. Methods Between June 2002 and September 2008, 40 patients with cubital tunnel syndrome caused by cubitus valgus deformity underwent anterior subcutaneous ulnar transposition. Related factors wasanalysed through logistic regression analysis using scoring standard recommended by Yokohama City University. Results All 40 patients were followed up 27.5 months on average (range, 12-75 months). The duration of cubitus valgus deformity, cubitus valgus deformity angle, and the duration of paraesthesia and muscular atrophy were identified as related factors for ulnar neuropathy and the odds ratios were 1.005 (P=0.045), 9.374 (P=0.000), and 4.358 (P=0.010), respectively. The related prognosis factors were duration of paraesthesia and muscular atrophy, deformity angle, and age at surgery, with odds ratios of 8.489 (P=0.000), 2.802 (P=0.030), and 4.611 (P=0.031), respectively. Conclusion Related factors for ulnar neuropathy are durations of cubitus valgus deformity, cubitus valgus deformity angle, and duration of paraesthesia and muscular atrophy. Related factors for prognosis include age at surgery, cubitus valgus deformity angle, and duration of muscular atrophy. Early anterior subcutaneous ulnar transposition should be performed in patients with cubital tunnel syndrome caused by cubitus valgus deformity
ObjectiveTo explore the risk factors influenced postoperative complications of colon cancer. MethodsIn this study, 114 patients diagnosed definitely as colon cancer were enrolled from January 2009 to April 2010 in this hospital. The patients were divided into the complication group and non-complication group according to the occurrence of postoperative complications during hospital day. Furthermore, clinicopathological features and operative parameters of patients were compared in two groups, and independent factors for postoperative complications were identified by multiple regression analysis. ResultsThere were statistical differences between two groups in operation time (t=2.034, P=0.032), diabetes mellitus (χ2=5.920, P=0.015), differentiation degree of tumor (χ2=7.163, P=0.028), hospital stay (χ2=0.411, P=0.026), and ASA grades (χ2=11.585, P=0.009). The morbidity of patients with operative time gt;200 min was significant higher than that ≤100 min (χ2=8.884, P=0.003) and 100-200 min (χ2=7.318, P=0.007). The morbidity of patients with ASA Ⅳ grade was higher than that with ASA Ⅰ grade (χ2=13.426, P=0.000). For tumor differentiation, the morbidity of patients with well-differentiated tumor was higher than that with moderately differentiated tumor (χ2=4.950, P=0.026) and poorly differentiated tumor (χ2=7.476, P=0.006). The hospital stay (P=0.009), age (P=0.024), diabetes mellitus (P=0.018), and ASA grade (P=0.001) were the independent factors for postoperative complications by multivariate regression analysis. ConclusionThe physical quality indexes are the mostly common risk factors of postoperative complications for colon cancer, emphasizing on the high-risk factors and making a targeted and individual treatment plan for each patient are of great important to improve the prognosis.
ObjectiveTo discuss the etiological factors and risk factors for peptic ulcer hemorrhage with negative Helicobacter pylori (HP). MethodsA total of 182 patients with peptic ulcer treated in our hospital from January 2010 to December 2012 were chosen in our study. There were 85 cases of hemorrhage among them, with 50 HP positive and 35 HP negative ones. The other 97 patients were without hemorrhage. Etiological factors and correlated risk factors for peptic ulcer hemorrhage with HP negative were analyzed. ResultsHP negative rate of the hemorrhage group was 41.2%, while that rate of the non-hemorrhage group was 14.4%, and the difference was significant (P<0.05). The patients with peptic ulcer hemorrhage with negative HP had correlations with age, sex, wine drinking, taking non-steroidal anti-inflammatory medicine and so on. ConclusionPeptic hemorrhage is easily complicated with peptic ulcer with negative HP, and it is intimately correlated with patients' age, sex, wine drinking history, and taking non-steroidal anti-inflammatory medicine, etc.
Objective To investigate the clinical characteristics and death risk factors of patients with community acquired pneumonia and sepsis. Methods Data of 350 patients with community-acquired pneumonia and sepsis admitted to the Intensive Care Unit of Third Xiangya Hospital of Central South University from January 2015 to October 2021 were retrospectively analyzed, and their basic characteristics, laboratory results and treatment were analyzed. Results The absolute value of white blood cell, neutrophil ratio, absolute value of neutrophil, inflammatory index, liver and kidney function, coagulation function, cardiac enzymology, lactic acid and sequential organ failure evaluation score of patients with community acquired pneumonia sepsis in the non-survival group were higher than those in the survival group. Logistic regression analysis showed that respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine and lymphocyte ratio may be independent risk factors for 28-day death in patients with community-acquired pneumonia and sepsis.The receiver operating characteristic curve shows that the combination of the above indicators to predict the risk of death of patients has the best sensitivity, specificity and maximum area under the curve, which is superior to the prediction value of individual variables. Conclusions Patients in the non-survivor group of community-acquired pneumonia sepsis had more severe inflammatory response and organ function impairment. Respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine, lymphocyte ratio and other indicators are independent risk factors for death of patients with community-acquired pneumonia and sepsis, which have better prognostic value when combined.
ObjectiveTo construct a structural equation model of the mechanism of the role of medical humanities literacy in job competency and to conduct empirical analysis to verify the supporting role of medical humanities literacy in cultivating job competency. MethodsLiterature research was conducted to select the initial indicator system for medical humanities literacy and job competency, and then a conceptual model was constructed. Questionnaire data from four hospitals in Chengdu were collected. Through exploratory factor analysis, an indicator system for medical humanities literacy and job competency more suitable for the research population was obtained and the conceptual model was adjusted. Finally, the positive mechanism of medical humanities literacy on job competency was verified using confirmatory factor analysis (structural equation model). ResultsThe Cronbach's alpha coefficient of the overall questionnaire involved in the exploratory and confirmatory factor analyses was greater than 0.9, and the KMO values of the questionnaire were greater than 0.8, with a Bartlett's sphericity test P value less than 0.01, indicating good reliability and validity of the questionnaire. The model fit of the structural equation model met the requirements, with a chi-square degree of freedom ratio (CMIN/df) of 2.768, root mean square error of approximation (RMSEA) of 0.077, comparative fit index (CFI) of 0.891, normalized fit index (NFI) of 0.840, and incremental fit index (IFI) of 0.891. ConclusionThe improvement of individual characteristics in job competency is mainly influenced by medical humanities knowledge and spirit. The improvement of cognitive characteristics in job competency is mainly influenced by medical humanities knowledge and ability. The improvement of achievement characteristics in job competency is mainly influenced by medical humanities ability and spirit. The improvement of management characteristics in job competency is mainly influenced by medical humanities spirit.
Objective To investigate and analyze the employment status and related influencing factors of maintenance hemodialysis (MHD) patients. Methods MHD patients from four hemodialysis centers in Beijing between January 2020 and January 2021 were selected. The baseline data and clinical data of patients with long dialysis interval were collected. An anxiety and depression survey was conducted on the patient. Results A total of 108 MHD patients were included. Among them, 41 patients were working and 67 patients were not working. Among the 41 patients at work, there were 3 workers, 1 farmer, 14 company employees, 6 public institution employees, 11 self-employed, 5 freelancer and 1 other. Among the 67 patients who did not work, 8 patients had the ability to work but did not work. Body mass index was an independent influencing factor for employment in MHD patients [odds ratio=1.135, 95% confidence interval (1.017, 1.266), P=0.024]. Conclusion The nutritional status of MHD patients should be taken seriously to improve their employment rate.
Objective To investigate the prognosis factors of postoperative cardiac complications in esophageal cancer patients co‐morbidated with coronary artery disease. Methods Clinical data of the patients with esophageal cancer surgery and concomitant coronary heart disease admitted to the esophageal surgery department of our hospital from December 2019 to June 2023 were collected. They were divided into two groups based on the occurrence of postoperative cardiac complications. Using postoperative cardiac complications as the dependent variable, we established a multivariate logistic regression analysis model to explore the relevant influencing. ResultsA total of 223 patients were collected, including 148 (70.71%) males and 75 (20.29%) females with an average of 71.78±6.31 years, ranging from 53 to 88 years. There were 71 (31.84%) patients experiencing at least one cardiac complication, including 2 patients of acute coronary syndrome, 13 patients of cardiac insufficiency, and 59 patients of new postoperative arrhythmias. The results of univariate analysis showed that age, systemic immune-inflammation index, pulmonary infection, respiratory failure requiring invasive ventilation, ARDS, acute delirium, additional drainage for pleural effusion, and acute renal insufficiency were risk factors for postoperative cardiac complications (P<0.05). The results of the multivariate logistic regression model showed that age (OR=1.062, 95%CI 1.008-1.120, P=0.024) and ARDS (OR=7.690, 95% CI 3.498-16.903, P<0.001) were independent risk factors for postoperative new cardiac complications in esophageal cancer patients with concomitant coronary heart disease. Conclusion Strengthening perioperative management of esophageal cancer, from strict preoperative evaluation to the treatment of postoperative complications, with particular attention to indicators such as age and ARDS, is crucial for improving the prognosis quality of patients with coronary heart disease complicated with esophageal cancer after surgery.
